Typically, taking three measurements in the tenor, two in alto, two in treble, string heights on all models except the D would measure:</FONT></DIV> <DIV><FONT face="Bookman Old Style">192mm-193-192 | 192-191 | 190-189 </FONT></DIV> <DIV><FONT face="Bookman Old Style">or something like it. I've seen as high as 193-194-193 sloping to as low as 188. I'd suspect undesirable plate warp, especially since the plate webbing usually somewhat mirrors this; but what do I know - I'm sure it's a Feature. Saw the tops off the treble hammers.</FONT></DIV> <DIV><FONT face="Bookman Old Style"></FONT> </DIV> <DIV><FONT face="Bookman Old Style">Bob D</FONT></DIV><BR><BR><BR><DIV><FONT style="color: black; font: normal 10pt ARIAL, SAN-SERIF;"><HR style="MARGIN-TOP: 10px">See what's free at <A title="http://www.aol.com?ncid=AOLAOF00020000000503" href="http://www.aol.com?ncid=AOLAOF00020000000503" target="_blank">AOL.com</A>. </FONT></DIV></BODY></HTML>
